ful Improvements in Rail-Joints, of which the following is aspecification.

An object of the invention is to provide a joint for effectivelyconnecting adjacent rail ends. For the purpose mentioned, use is made ofa clampbody for attachment to suitable ties and provided with sidepieces forming a longitudinally extending slot in which the rail endsare received, a supporting plate being interposed between the bases ofthe rail ends and the base of the clamp body, the said supporting platebeing provid d with a brace plate engaging one of the sides of each ofthe rail ends, the other sides of the said rail ends being engaged byone of the said side-pieces, serrations formed on the said supportingplate and a pin for insertion in one of the side pieces and adapted toengage the teeth of the said supporting plate to releasably lock thesaid supporting plate to thesaid clamp body.

Reference is to be had to the accompany ing drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is aperspective view of my rail joint. Fig. 2 is a transverse verticalsectional view, showing the pin for locking the supporting plate to theclamp body. Fig. 3 is a perspective view of the supporting plate, Fig. 4is a perspective view of the locking pin.

Referring more particularly to the views, I provide a clamp body 10,consisting of a base 11 terminating in flanges 12, provided with cut outportions 13 adapted to receive suitable spikes 14 for securing the clampbody 10 to ties 15.

The clamp body 10 is provided with integral upwardly extending sidepieces 16,

17 which form a longitudinally extending slot 18 in the clamp body 10,the side piece 17 being curved and extended upwardly a greater distancethan the side piece 16. Rail ends 19 are mounted in the slot 18 of theclamp body 10 with webs 20 of the rail ends and sides 21 of the basesthereof, engaged by the side piece 17 as shown in Figs. -1 and 2.Interposed between the bases 22 of the rail ends and the base 11 of theclamp body 10 is a supporting plate I 23 provided with an integral baseplate 24,

reposing on the base 11 of the clamp body 10 and the mentionedsupporting plate 23- is provided with an integral curved upwardlyextending brace plate 25 engaging sides26 of the bases- 22 and sides 27of the webs 20 of the rail ends, the upper end of the brace plate 25being adapted to abut against heads 28 of therail ends. that thesupporting plate 23 engages the outer sides of the rail ends, whiletheside Thus, it will be'seen,

piece 17 engages the inner sides of the rail. I

ends and' the side piece 16, being shorter than the side piece 17,engages the supporting plate 23 at the point where the suport-ing platecurves upwardly from the ase 24 and around the outer edges of the" bases22 of the rail ends.

The supporting plate 23, at the point where the same curves around theouter edges ofthc bases of the rail ends, is provided on its outer sidewith integral serrations or teeth 29 and formed in the side piece 16 areopenings 30 having cut away p0r-' tions 31, the said openings beingadapted to a receive squared pins 32, each pin being 'received in eachof the openings 30 and having an edge thereof extending through the cutawayportions 31 and engaging the teeth'29 to lock the supporting plate23 to the clamp body 10.

In the preferred manner of applying my device, I firstslide the clampbody 10 over the rail ends, the mentioned clamp body being preferablyinclined with one side of the clamp body higher than the other sidethereof, so;

that the base 11 of the clamp body will be at an angle to the bases ofthe rail ends, thus permitting the clamp body to bemore easily engagedwith the rail ends. The clamp body is then permitted to repose upon theties and the bases of the rail ends resting on the base of the clampbody and then by slightly raising the railends, the supporting plate isengaged with the clamp body so as to lie between the outer-edges of therail ends and the clamp body, with. the base of ;the supporting plateinterposed between the rail ends, after which by subjecting the supporting plate to a series of blows at one end base of the clamp body andthe basesof the thereof, the mentioned supporting plate will be forcedinto frictional engagement with the clamp body and the rail ends untilthe teeth or serrations 29 are positioned oppo- -sitely to the cut awayportions 31 so that the pins 32 can be inserted in the openings toengage the teeth 29, thus locking the supporting plate to the clamp body10 as has been heretofore mentioned, the clamp body having beenpreviously secured to the ties by the bolts or spikes 14.

With a device of the character described, the rail ends will beprevented from moving transversely to the clamp body while at the sametime the rail ends will be permitted to move longitudinally for thepurpose of allo ing for the expansion and contraction of t 1e rails, dueto heat or cold.

Having thus fully described the invention,

What I claim as new, is A o1nt for two rail ends, including an 'tnglefish plate adapted to engage with one of the sides of the rails andhaving a and which further adapted to registev" with one of theplurality of serrations upon the vertical connecting member of the fishplate, a headed pin adapted to be inserted within the openings and torest within the pocket and to engage with the serrations in both thefish plate and chair, and pihe meme bers engaging with the longitudinaledges
